Thank you so much for your replies. I appreciate you sharing your experiences. I have no problems at this time. It is only from reading of others' troubles and seeing what the beetles do to the milkweeds on the side of the road that I was looking for ideas to prevent this if possible.
And Horntoad! I knew I saw that idea, but couldn't remember what those things were called. I am having a horrid time with Corn Rootworm adults on my native hibiscus, but oh! I better not get started on this thread because I am miffed about this.
